Answer:
The density of old trunk is [tex]11.3 g/cm^3[/tex] and it is equal to the density of metal lead.
Explanation:
Mass of the trunk , m= 222 g
Length of the cubic trunk = 2.7 cm
Volume of the cube = [tex]a^3[/tex]
Density of the truck = [tex]\frac{Mass}{Volume}[/tex]
[tex]D=\frac{m}{a^3}=\frac{222 g}{(2.7 cm)^3}=11.2787 g/cm^3\approx 11.3 g/cm^3[/tex]
The density of old trunk is [tex]11.3 g/cm^3[/tex] and it is equal to the density of metal lead.
